Double-sided touch screen POS cash register printer FAQ:
1, the font problem:
Sometimes in some special cases, printing Chinese is garbled. At this time, you need to upgrade the font, because if the upgrade is not correct, it will cause irreparable damage to the printer. Therefore, the upgrade generally needs to be performed by the manufacturer. If the user has this situation, please Contact the manufacturer as soon as possible, send the printer to the manufacturer, and upgrade it by a professional.
2, double-sided touch screen POS cash register printer jam problem:
Sometimes the printer may have a paper jam. Pressing the open button does not open the cover. This is because the paper is stuck in the cutter. At this point, you can open the front cover of the printer and you will see the entire set of cutters. The white adjustment wheel can be rotated to adjust the front and rear of the cutter. Generally, the paper jam occurs because the cutter position is too far forward and can be adjusted backwards appropriately.
3. Check the paper problem:
Sometimes the printer does not work after it is turned on, the paper light does not stop flashing, indicating that the paper does not detect the paper and does not work. However, the paper printer placed in the whole roll still does not work. In this case, please confirm whether the thermal paper used is 80. The paper is wide, and now there are some irregular thermal papers on the market that are only 79 wide. Please purchase standard 80 wide thermal paper.
4, paper cutting problem:
Sometimes the POS cash register printer will cut only half of the paper cut, and the other half should be manually torn. It is very unattractive. At this time, the staff needs to open the top cover of the printer, and the cutter groove will be composed of two upper and lower iron pieces. In the middle, a small spring is lifted up, and there are two small hooks on the left and right. If the printer is left without cutting the paper, the small hook on the left side can be slightly tilted with a small screwdriver. If it is the right side, it can be turned to the right.
5, printing problems:
Printing problems generally occur in three situations: print blur, print half of the print, blank print. First, the printing blur is caused by two reasons, one is that the thermal head is damaged, and the other is caused by the texture of the printing paper. In this case, you can check the printing paper first, replace the other printing paper, and purchase the printing paper to purchase a paper with smooth texture, no impurities, and good flexibility. If it is not possible to replace the paper, it is that the thermal head is damaged and needs to be returned to the factory for replacement. Secondly, the printwriting is only displayed in half, which is also caused by the damage of the thermal head. At this time, it needs to be returned to the factory for replacement. Finally, the blank print is also related to the thermal head. First check if the thermal head is deformed and whether it is stuck in the original position. If it is tilted or deformed, it will cause the paper to be inaccessible and cause blank printing. If everything is normal, then the thermal head is damaged and can only be returned to the factory for replacement.
